To @ZZ 'whom it may concern Be it llniown that l, GEORGE M. lAsT, e oitizen 'of the United States, residing et llnvilnd, in the county of Peudling and' State of @hiel lieve invented n new and useful Surieles-i?ulverizer,l of which the following; is e' specification.

lhis invention rela-tes to improvements in surface pulveri'/iers.v

in ebjeet ofthe present invention is to provide' surface pulverizer which will thoroughly breek up and level the ground over which it passes.

A, further ebjeet is to provide e surfeee ortion so that the depth to which the groun is treated iney be varied.

ilurther object is to provide surface pulverizer including :i plurality of engulznly disposedhorizentelly extending egi-` te-tors arranged in series, with the angulerity or one series opposite to the angulerity of the series next edgeeent thereto,' and to include therewith en adjustable portion4 which iney be raised or lowered end so 'arranged that tlieuction of vthe agitetors is modified or amplified thereby,

il further object is to provide a. surfacel pulverizer with engulerly disposed horizontal einending` egitetors arranged in series upon the under surface end with parallel Cross members errenged along the top sureee so tiret 'libe surface pulverizer may be reversed end the cross members used 'to smooth the dition.

lllith the foregoing and other objeets in View which will appesi: as the description proceedsj tiieinven'tion resides in the combinetion end arrangement of ports end in the details oi" construction hereinafter described and claimed, it being understood that changes in the precise embodiment of 'the invention herein disclosed7 een be mede Within the scope ef what is claimed, Without departing' from the spirit oi the invention.

ln the drawings eeeompiniying this speei ficution and lioizfi'iing port thereof, the preferred embodiment or .my invention is illustrated, in ivhieln*V Figure l is e. tsp plan view of .my inproved surfnee pulverizer. Fig. 2 is o cross secsionel view t'nereoie taken on the line 2--2.

eerth and leave it in such con-' zontally, end ere inclined :it substantielly 4:5 degrees with respect to the .transverse median line oli the freine deiined by the beams 3 end Ll. is mentioned the agitetors are arranged in e series, eeeh' series being lcinnposed of e plurelity of parallelly diey posed egitetors extending between two olf' the longitudinal beams 4, Four series have 'been illustrated in the present drawings and it is to be noted that the egitetors of one series extend et right angles to the egitetors of the next adiecent series, and -if'urthermore that theends ef the agitetors extend juxtaposed to and approximately central of the egitntorsof the next adjacent series, es clearly illustrated in Fig'. l, The egitators are formed of angle bers with the one delige f thereoll extending substantially. horizontally and the other extending perpendieulerly downward therefrom. Ellie entire freine and egitetors ere ,rigidly secured together by suitable rivets 6 or other equivalent ineens.

Draft bars 7 are rigidly secured to the longitudinal beams l and are provided with the hooked ends 8 to which e @hein 9 or other equivalent ineens is secured whereby the (li-lift animal may be secured to the pulverizer and exert' etractive e'ort thereon.

The segmental bar at its remote v extremity is provided with the notches 'l'' which may be engaged by a hand operated latch 18 secured to the leyer`19 carried by the auxiliary frame. The lever 19 is pro.-A vided with the opening 20 extending therethrough'` receiving the segmentalv bar 1d therein for the guidance. thereof. '.Thus,`

when it is desired to raise or lower the teeth 13, the hand latch is withdrawn which allowsthe auxiliary frame to swing about the eyes 10 into some new and desired position. The hand latch is then again-inserted in place in engagement with one of-'the notches 1.7 which securely locks .theteeth 13 in any adjusted I position Y with a respect. to the eg'itators 5.

Having thus described my invention, what I claim is z- 1. A harrow comprising a'frarne including side beams, a plurality of angle-sl1a`pe parallel extending beams secured thereto and arranged withthe vertical flange projecting upwardly, a plurality ot angle shapedserially arranged agitators secured to saidbeams and arranged with the verti- Ycal -finge extending downwardly.

A harrow comprising a' frame including side beams, a plurality of angle-shape 'parallel extending beams secured thereto and arranged with the vertical flange projecting upwardly, a plurality of angleshaped agitators, said agitators arranged vin seriesextending across the frame, the agitators of one series beingdisposedt right angles to and `terminating approximately central of the agitators of the adjacent series. v 3. A barrow comprising a frame including side beams, a plurality of angle-'shape and arranged with the vertical ange projecting upwardly, a plurality of angleshaped serially arranged agitators secured to said beams and' arranged with the vertical flange extending downwardly, and a seat detachably secured to said frame.

4. A harrow comprising a reversible frame including sidebeams, a plurality of angle-shape /arallel extending beams securedthereto and arranged with the verof angle-shaped serially arranged agitators secured to said beams and. arranged with vthe vertical flange extending downwardly, and a seatdetachably secured to said. frame.

5. A harrow comprising a frame includparallel extending beams secured thereto 'and arranged with the vertical flangeprojecting upwardly, a plurality of anglel Ijahaped serially arranged agitators secured Y, tir-said beams and arranged with the vertical liange extending downwardly, and means secured to the'rear extremity of said frame,l contacting with and supported upon the ground adapted to raise the rear end of said frame and hold the same in adjusted elevated positions. l
